A case of searching the moon, sun, comet, etc. will be described with reference to the flowchart showing the star search routine of FIG.

First, electric power is supplied to the navigation device 33 by a user who is a passenger in the vehicle.
Then, in the system control unit 41, the passenger is provided with the input means 17
It is determined whether or not the display content switching request, that is, the display of the celestial object search is set by the input operation of. When recognizing that the display of the celestial body search is set, the display means 15 controls to display a screen display regarding the celestial body search.

That is, the system control unit 41 causes the display means 15 to display a menu screen for celestial object search.
Specifically, whether it is a search for observing stars as a celestial body, a search for observing artificial satellites that are artificial celestial bodies as a celestial body, a search for observing a solar eclipse, a lunar eclipse, etc.
Display a menu screen that prompts you to enter settings by selecting a search item such as a search for observing sunrise or sunset. Then, as shown in FIG. 2, when the system control unit 41 recognizes that the search for observing stars and the like has been set and input by the input operation of the input means 17 (step S1), the user who is the observer Display means 1 for displaying a screen prompting for inputting setting of observation information such as desired observation conditions
Control to display on 5.

As the observation information, for example, a search for a destination for observing an astronomical object, a search for an astronomical object to be observed, a search for a place where the astronomical object can be seen neatly, or a time zone for observing is searched. Or something. The destination is set to a specific place such as the summit of Mt. Fuji, a region such as Kujukurihama, or a region within 20 km from the current position.

When the system control section 41 recognizes the input operation of the observation information by the input means 17, it sets the observation information operated by the input operation and temporarily reads out the setting information RAM 48 of the storage means 42. (Step S2).

Further, the system control unit 41 uses the GPS sensor 44 to detect the GP in order to grasp the set destination.
The navigation radio wave 55a output from the S satellite 55 is received, and the current position of the vehicle is measured by the position information acquisition means 51 to acquire the position information (step S3). The location information is
It is output to the setting information RAM 48 of the storage means 42 and temporarily stored in a readable manner.

Then, when the destination is set as the observation information, the system control unit 41 causes the map information acquisition unit 52 to acquire the map information of the destination from the map information database 46 of the storage unit 42 (step S
4). If the destination is not set, that is, only the celestial object to be observed is set in step 2, only the observation time zone is set, or if only the star is desired to be set, the map information to be acquired is, for example, The map information of the whole area of Japan or the range where the vehicle can move within a half day from the current position, which is the position information acquired in step S3, is acquired.

After that, the system control section 41 acquires the astronomical observation information from the base station 70 by the communication means 62. That is, for example, time information which is the current season and time is acquired from the Meteorological Agency or an observatory via the network and the base station 70. Here, for example, when an celestial body such as a star to be observed is set as the observation information in step S2, the celestial body information regarding the set celestial body is also acquired. Then, the acquired astronomical observation information is acquired by the astronomical information acquisition means 66 and the time information acquisition means 68, and is temporarily stored in the astronomical observation information RAM 47.

Note that the season and time are the artificial satellite GP.
The navigation radio wave 55a output from the S satellite 55 may be received by the GPS sensor 44 via the GPS antenna 44a and acquired based on the received navigation radio wave 55a. In addition, for example, when only the star is desired to be viewed in step S2, only the time may be acquired as the time information and the season and celestial body information may not be acquired.

Then, the astronomical observation site search means 65 of the system control unit 41 determines whether or not astronomical observation is possible based on the observation information stored in the setting information RAM 48 and the time information stored in the astronomical observation information RAM 47. It is determined (step S5). For example, when an celestial body such as a star to be observed is set, it is determined whether the celestial body can be observed from the season and the time. Further, in step S5, for example, when the observation time zone is set in step S2, it is determined whether or not astronomical observation is possible at that time. When it is determined that the observation cannot be performed in step S5, the process returns to step S2, and the display prompting the setting of the observation information is performed again.

If it is determined in step S5 that it is observable, the communication means 62 causes the base station 70
Get astronomical observation information from. That is, for example, the weather information of the destination is acquired from the Meteorological Agency via the network and the base station 70. As the weather information, for example, when the destination is not the current position, predicted weather information at the time of arrival at the destination is acquired. Here, the time of arrival at the destination can be obtained by searching the optimal travel route from the current position to the destination by the destination guiding means 54 and calculating the travel time on the searched travel route. . The acquired weather information is acquired from the communication means 62 by the weather information acquisition means 67 of the astronomical observation information acquisition means 64, and is temporarily stored in the astronomical observation information RAM 47.

Then, the astronomical observing site search means 65 of the system control unit 41 determines whether or not the weather is observable with the naked eye based on the weather information stored in the astronomical observation information RAM 47 (step S6). ). This step S
When it is determined in 6 that the weather cannot be observed due to the irregular weather, the process returns to step S2, and the display prompting the setting of the observation information is performed again.

If it is determined in step S6 that the celestial body is observable, the celestial body observation site search means 65 calculates the direction in which the celestial body to be observed can be seen. That is, the astronomical observation site search means 6
Based on the celestial body information and the map information acquired in step S4, 5 calculates which direction on the map data the direction in which the celestial body is viewed is on the map data (step S7).

Furthermore, the astronomical observing site search means 65 is based on the map information, and based on the height information of the terrain such as the buildings and mountains around the destination, is there any building or mountain that obstructs the observation? It is determined whether or not (step S8). Then, in step S8, when the astronomical observing site searching means 65 determines that there is a building or a mountain that obstructs the observation, it is determined that the celestial body cannot be seen from the destination, and the process returns to step S2.

In step S8, when the astronomical observing site search means 65 determines that there is no building or mountain that obstructs the observation, the destination is set as a good observing site, and this setting is made. The observed location is output to the destination guiding means 54 of the navigation control means 43. Then, the destination guiding means 54 acquires the setting information R acquired in step S3.
A travel route that can be traveled by the vehicle from the current position, which is the position information stored in the AM 48, to the observation site is searched (step S9).

Then, the navigation control means 43
The searched moving route and the observing place set by the astronomical observing place searching means 65 are displayed on the display means 15 as a list to prompt the user to decide one of the moving routes (step S10). As the display on the display unit 15, for example, as described above, the observable region or the specific place at the destination is displayed.
It may be displayed in a display form in which it is easy to identify each color or flash.

When a predetermined moving route or a specific observation place in the destination is set by the input operation of the input means 17 by the display in step S10, the star search routine is terminated and the navigation system 36 is instructed. Switch to display a message that guides you to the observation location. Further, in step S10, when the moving route or the specific observation place is not set, it is determined that the search result does not match the desired condition, the star search routine is terminated, and, for example, the menu screen is displayed. Let

(Search for Artificial Satellite) A case of searching for an artificial satellite which is an artificial celestial body as an astronomical object will be described with reference to the flowchart showing the satellite search routine of FIG.

In the case of the satellite search, as in the case of the star search, the system control unit 41 determines whether or not the display content switching request, that is, the display of the celestial object search is set by the input operation of the input means 17. . Then, the system control unit 4
1 recognizes that the display of celestial object search is set,
The display means 15 is controlled to display a display screen relating to celestial object search. Then, the system control unit 41 causes the display unit 15 to display a menu screen for celestial object search. From this display, as shown in FIG. 3, when recognizing that the search for observing the artificial satellite has been set and input by the input operation of the input means 17 (step S11), the system control unit 41 causes the user who is the observer. Displays a message prompting you to enter the observation information settings such as the desired observation conditions.

When the input means 17 recognizes the input operation of the observation information, the system control unit 41 sets the input observation information and temporarily stores it in the setting information RAM 48 so that it can be read (step S12).

Further, the system control section 41 controls the navigation radio wave 5 output from the GPS satellite 55 by the GPS sensor 44.
5a is received, the current position of the vehicle is measured by the position information acquisition means 51, and position information is acquired (step S13).
The position information is output to the setting information RAM 48 and temporarily stored in a readable manner.

When the destination is set as the observation information, the system control unit 41 causes the map information acquisition unit 52 to acquire the map information of the destination from the map information database 46 of the storage unit 42 (step S1
4). If the destination is not set, that is, only the celestial object to be observed is set in step 12,
If only the time zone to be observed is set, or if you simply want to see the stars, etc., the map information to be acquired may be, for example, within Japan or within half a day from the current position, which is the position information acquired in step S13, by vehicle. Get map information of the range that can be moved to.

After that, the system control section 41 acquires the astronomical observation information from the base station 70 by the communication means 62. That is, for example, time information which is the current season and time is acquired from the Meteorological Agency or an observatory via the network and the base station 70. Then, the acquired astronomical observation information is acquired by the time information acquisition means 68, and is temporarily stored in the astronomical observation information RAM 47 of the storage means 42. Note that this time information is also output from the GPS satellite 55 as described above, and the GP
It can also be acquired based on the navigation radio wave 55a received by the S sensor 44.

Then, the astronomical observing site search means 65 of the system control section 41 can perform astronomical observation based on the observation information stored in the setting information RAM 48 of the storage means 42 and the time information stored in the astronomical observation information RAM 47. It is determined whether or not (step S15). For example, when the time information is daytime, it can be determined that it cannot be observed.
In step S15, for example, step S12
If the time zone for observation is set in, it is judged whether or not the satellite observation is possible at that time. When it is determined that the observation cannot be performed in step S15,
Returning to step S12, the display prompting the setting of the observation information is executed again.

If it is determined in step S15 that it is observable, the communication means 62 causes the base station 7
Acquire astronomical observation information from 0. That is, for example, the weather information of the destination is acquired from the Meteorological Agency via the network and the base station 70. As described above, as the weather information, for example, when the destination is not the current position, the predicted weather information at the time of arrival at the destination is acquired. Here, the time of arrival at the destination is obtained by calculating the navigation control means 43 of the system control unit 41 as described above.
